“OpenClonk is a free multiplayer action game where you control clonks, small but witty and nimble humanoid beings. The game is mainly about mining, settling and fast-paced melees. OpenClonk is also not just a game but also a versatile 2D game engine that offers countless possibilites to make own mods.”
I planned on releasing a how-to for building openclonk from source. However, those snarky devels decided to (finally) release a Linux binary. This is a bit of the recorded gameplay from that project.
Fun game, give it a go.
